Cry It Out (CIO) is a broad phrase that refers to any method of training a child to sleep through the night that involves allowing a baby to cry for a given amount of time. Though often associated with Dr. Richard Ferber, Ferber never used the term in his book, Solve Your Child's Sleep Problems (Compare prices). Ferber and many other sleep experts say that in some cases crying it out is a necessary tool for getting children to sleep through the night. However, crying it out is a controversial method that parents should fully understand before trying with their baby.
